Avoid using tweezers to remove the stinger, since squeezing it may release more venom. Wash the area of the bite with soap and water. Place a cold compress or ice pack on the area for about 10 minutes at a time to help reduce pain and swelling

Explanation:

so basically B, i hope this helps and its not too late!

First, remove the stinger with mild force and wash the area thoroughly with soaps. Apply cold compress or ice packs to avoid swellings. Hence, option B is correct.

Histamines are chemical substances in our body generating allergic action on skin. When some allergens or stimuli are exposed with our skin, histamine is produced.

Similarly if an insect with stinger bite on our skin, histamine is produced and allergic reactions occurs in our body. The bitten area has to be washed for minutes with soap. If any stinger persist on skin remove it.

Cold compress or ice packs are very helpful if the skin starts to swell. If any pain occurs, lower doses of pain killers can be taken. If necessary antihistamines have to be taken.

Answer:\(d=6.2\times 10^{-6}\ m\)

Explanation:

Given that,

The diameter of a human blood cell is 0.0000062 m. We need to express in scientific notation.

Any no can be written in scientific notation as follows :

\(N=n\times 10^m\)

n and m are real no and integer respectively

0.0000062 has 5 zeroes before 6. It means its scientific notation is as follows :

\(d=6.2\times 10^{-6}\ m\)

The error in the estimation of g is 5%

Take the difference between the actual and anticipated values. Start by deducting the actual value from the anticipated value.

Multiply by the true value. Divide the calculation's outcome by the actual value after determining the discrepancy between the actual and predicted values. ...

Add 100 to the value.

p = 36 kgm/s

The subatomic particle that is not a part of the nucleus which stays bound to the atom is the electron and is to maintain relative stability.

This is defined as a sub atomic particle which is negatively charged and revolve around the nucleus. In an atom the number of electron is usually equal to the number of the proton which is positively charged and present in the nucleus.

The electron not being in the nucleus is a a result of it wanting to maintain stability because its presence will produce a wavelength which will break the nucleus apart.

Answer:D

Explanation:

Given

Same force is applied to each ball such that all have different masses

and Force is given by the product of mass and acceleration

\(F=m\times a\)

\(a=\frac{F}{m}\)

So acceleration of ball A

\(a_A=\frac{F}{0.5}=2F\)

acceleration of ball B

\(a_B=\frac{F}{0.75}=\frac{4F}{3}=1.33F\)

acceleration of ball C

\(a_C=\frac{F}{1}=F\)

acceleration of ball D

\(a_D=\frac{F}{7.3}=\frac{F}{7.3}\)

It is clear that acceleration of ball D is least.

The angle of projection given that the range is 256√3 m and the maximum height reached is 64 m is 30°

R = u²Sine(2θ) / g

256√3 = u²Sine(2θ) / 9.8

Cross multiply

256√3 × 9.8 = u²Sine(2θ)

Divide both sides by Sine(2θ)

u² = 256√3 × 9.8 / Sine(2θ)

H = u²Sine²θ / 2g

64 = [256√3 × 9.8 / Sine(2θ)] × [Sine²θ / 2 × 9.8]

64 = [256√3 / Sine(2θ)] × [Sine²θ / 2]

Recall

Sine²θ = SineθSineθ

Sine2θ = 2SineθCosθ

Thus,

64 = [256√3 / 2SineθCosθ] × [SineθSineθ / 2]

64 = 256√3 × Sineθ / 4Cosθ

Recall

Sineθ / Cosθ = Tanθ

Thus,

64 = 256√3 / 4 × Tanθ

Divide both side by 256√3 / 4

Tanθ = 64 ÷ 256√3 / 4

Tanθ = 0.5774

The pressure of the gas in the deodorant can when it is heated to 900 K is 9 atm.

Gay-Lussac's law states that the pressure exerted by a given quantity of gas varies directly with the absolute temperature of the gas.

It is expressed as;

P₁/T₁ = P₂/T₂

From the data:

We substitute our values into the expression above and solve for final pressure.

P₁/T₁ = P₂/T₂

P₁T₂ = P₂T₁

P₂ = P₁T₂  / T₁

P₂ = ( 3 atm × 900 K ) / 300 K

The mechanic will have to apply a force of 73.575 N to lift the vehicle using the hydraulic Jack.

To calculate the force the mechanic will have to apply, we first need to determine the pressure exerted by the weight of the vehicle on the surface area.

Pressure is defined as force per unit area, so we can use the formula:

Pressure = Force / Area

The weight of the vehicle is 1500kg, which is equivalent to a force of:

Force = mass x gravity

where;

Force = 1500 kg x 9.81 m/s²

Force = 14,715 N

The pressure exerted by the weight of the vehicle on the surface area of 10m² is:

Pressure = Force / Area

Pressure = 14,715 N / 10 m²

Pressure = 1471.5 Pa

Now we can calculate the force the mechanic will have to apply to the surface area of 0.05m² using the same formula:

Pressure = Force / Area

We know the pressure and the area, so we can rearrange the formula to solve for the force:

The kinetic energy of particle B at the instant when the particles are 3.0 m apart is 4.32 J.

The total energy of the system is conserved. The initial energy of the system is the electrostatic potential energy, which is given by:

U = k × (Q₁ × Q₂) / r

where:

U = potential energy in joules

k = Coulomb's constant (8.988 x 10⁹ N m²/C²)

Q₁ and Q₂ = charges in coulombs

r = distance between the charges in meters

In this case:

U = 8.988 x 10⁹ N m²/C² × (12 C × 5 Q) / (1.0 m) = 5.375 x 10⁻⁷ J

The final energy of the system is the kinetic energy of particle B. The kinetic energy is given by:

KE = 1/2 × m × v²

where:

KE = kinetic energy in joules

m = mass in kilograms

v = velocity in meters per second

Solve for the velocity of particle B using the conservation of energy equation:

KE = U

Substituting the expressions for KE and U gives:

1/2 × m × v² = 5.375 x 10⁻⁷ J

Solving for v gives:

v = √(2 × 5.375 x 10⁻⁷ J / m)

= 1.53 m/s

The kinetic energy of particle B is then:

KE = 1/2 × m × v²

= 1/2 × m × (1.53 m/s)²

= 4.32 J

Therefore, the kinetic energy of particle B at the instant when the particles are 3.0 m apart is 4.32 J.

a) Z = 58.0 Ω - j66.35 Ω ;  b) Imax = 0.515 A  ; c) i = 0.515 sin(200πt + 42.5°) ; d) i = 0.515 sin(200πt + 0.741 rad)  ; e)  If the inductance of circuit is 0.0969 H, then current will lag the voltage by same angle as in part (d).  ;f) |Z| = 60.

Measure of the opposition that electrical circuit presents to the flow of alternating current is called impedance.

(a) Impedance (Z) of the circuit is : Z = R + j(XL - XC)

Inductive reactance and capacitive reactance are : XL = 2πfL

XC = 1/(2πfC)

XL = 2π(100 Hz)(150 mH) = 94.25 Ω

XC = 1/(2π(100 Hz)(99.0 µF)) = 160.6 Ω

Therefore,  impedance of the circuit is: Z = 58.0 Ω + j(94.25 Ω - 160.6 Ω) = 58.0 Ω - j66.35 Ω

(b) Maximum current (Imax) in the circuit is : Imax = Δv / |Z|

Δv is amplitude of the voltage

|Z| = √((58.0 Ω)² + (-66.35 Ω)²) = 87.4 Ω

Therefore, maximum current in the circuit is: Imax = (45.0 V) / (87.4 Ω) = 0.515 A

(c) The phase angle (θ) between the voltage and current is : tan(θ) = (XL - XC) / R

tan(θ) = (94.25 Ω - 160.6 Ω) / 58.0 Ω = -0.959

Therefore, phase angle is: θ = -42.5°

Equation for the current is: i = Imax sin(ωt - θ)

ω is angular frequency in radians per second. Angular frequency is : ω = 2πf = 2π(100 Hz) = 200π rad/s

i = 0.515 sin(200πt + 42.5°)

(d) Phase angle in radians is: θ = -42.5° = -0.741 rad

i = 0.515 sin(200πt + 0.741 rad)

(e) The condition for the current to lag the voltage by the same angle as in part (d) is: ωL - 1/(ωC) = tan(θ)R

L = (tan(θ)R + 1/(ωC)) / ω

L = (tan(-42.5°)(58.0 Ω) + 1/(2π(100 Hz)(99.0 µF))) / (2π(100 Hz))

L = 0.0969 H

Therefore, if the inductance of circuit is 0.0969 H, the current will lag the voltage by the same angle as in part (d).

(f) The maximum current in the circuit is given by the same formula as in part (b), with the impedance |Z| calculated using the inductance found in part (e).  |Z| = √((58.0 Ω)² + (-18.99 Ω)²) = 60.

Answer: 5990 kJ :)

Explanation: a p e x <3

The amount of thermal energy needed to boil 2.65 kg of water at its boiling point is 5990 kJ. So, the correct answer is option C.

Thermal energy is the energy that is generated by the movement of particles within a substance or system. It is a type of internal energy and is directly related to the temperature of the system. The faster the particles are moving, the more thermal energy the system has. Thermal energy can be transferred from one system to another through the processes of conduction, convection, and radiation. It is a form of energy that is used in many different applications, such as heating homes and buildings, powering engines, and cooking food.

Here in the Question,

To calculate the thermal energy needed to boil the water, we can use the formula,

Q = m x L

where Q is the thermal energy, m is the mass of the water, and L is the latent heat of the vaporization of water.

Q = m x L

Q = 2.65 kg x 2260 kJ/kg

Q = 5990 kJ

Therefore, 2.65 kg of water will require 5990 kJ of thermal energy to reach its boiling point.
